To all whom'it may concern),

Be it known that I, JOHN E. MINTnn, a citizen of the United States, residing at Columbus, in the county of Muscogee and State of Georgia, have invented certain new and useful Im Jrovements in Automatic and Intermittentranders for Socket Sewer- Pipes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a .part of this specification.

For the past sixty years sewer pipe with sockets or bell ends has been manufactured in increasing quantiti s in, this country. Heretofore such pipe has always been branded by hand. Sewer pipes have never been successfully branded with an intermittent ribbon brander, such as is contemplated by this invention. a

This invention relates to brandersfor socket sewer pipe or hollow ware with bellshaped ends.

One of the objects of the invention is to provide means whereby the pipe will be branded with suitable designating char-ac ters as it passes from the forming die-to the receiving disk or socket former as the case may be. The pipes leave the forming press in a comparatively plastic state so that the walls are soft enough to take the impression of the brander pressed against them. v

I have provided means whereby an impressing brander may be brought into contact with the wall of the clay pipe as it is issuing from the press in such manner that the forming of the pipe and the impressing of the characters thereon may be accomplished as a single operation. The brander may be so constructed that the name of the manufacturer, a trade-mark or any other designating character or characters may be impressed upon the; outer wall of the pipe to designate the origin, quality, style or type so that when the pipe is burned in the kiln, the impressed character or characters will be a permanent part of the pipe.

In the drawings, I

Figure I is an elevational View of a pipe forming press of approved construction to which myinvention is applied.

Fig. II is a detail perspective view of the brander.

Fig. III is a view partly in section of the die support, showing a means for lubricating the perimeter of the brander.

The pipe-forming press may be of any approved construction and I have here shown acylinder 1, having a discharge end 2, through which the pipe may be extruded upon a socket former or disk 8, supported by a vertical plug shaft at. The brander is shown as being pivotally secured to a bracket 5, suitably supported upon the press and the brander is conveniently illustrated as consisting of a lever arm (5, pivoted to the bracket at 7, so that it may swing in a vertical plane, the upward swinging movement being resisted by the coil spring 8. one end of which is connected to the free end of the arm 6, at 9,'the other endbeing connected to a suitable support 10. A connection 11, is slidably movable upon the lever arm 6, but it may be held in any ad justed position by a set screw 12, which passes through the top thereof and which is adapted to impinge against the lever arm 6, so as to position the depending arm 13 thereon. The depending arm 13, is shown as consisting of a tubular member to receive a vertically adjustable shifting arm 14, having a curved end 15, to be engaged by a shifting finger, to be referred to hereinafter. The arm 14, however, may be held in any vertically adjustable position by the set screw 16, which passes through the bracket sleeve 17, to impinge against it. The depending arm 13, also serves as a support for a bracket 18, in which is a vertically adjustable carrying arm 19, adapted to be held in any. adjusted position by a set screw 20.

other pacl'ring material, as indicatediat 253 and a lubricantf26 is introduced thereinto,

the perimeter of the brander 22, will be lub'ricated by" wiping: contact withthe packingg and therefore liability of the characters sticking in the plastic wall of the pipe will be eliminated The-wheel maybe weighted as at 22, to cause the beginning of thebrand to be? first impressed against the at each operation.

pi e e ecured to the socket'iormer shaft 4, i's'a shifter finger 28, having a head 27, pro--- vided with elongated slots 29, and"30, where; by the finger 28', may be laterally adjus'ted so that it may be positioned properly with respect to the curved portion 15,1of the arm llt;

When the p'arts are assembled asshown in Fig. I, and the disk 3-,.is moved into close proximity with the end 2', for receivingthe extruding pipe, the finger 28',will contact with the curved portion 15, and movefaim 14;, away from the T cylinder; so (that the, b'rander will be shifted from the engaging position. As the pipe begins to extrude, however, andafte r the socketforniefB", has moved down farenough to carry the en larged portion or flange 31, of tli'epip'e" below the brander member, the finger 28, will have moved out of contact with the curved portion 15, ofshiftingarm 1'4, so" that the weight of the; brander, including the lever '6, arm 13, and arm. 19, will" swingdownward by gravity and. the thrust of'spring S, so'as to move the brander 22;

into pipe-engaging position, as shown: in-

Fig.1 The weight of the elements which support the pipe will be suflicient tocau'se an impression of the characters on the b'rander members into the clay wallof the pipe and this engagement will causelsutii cient' friction against the b'rander: to cause it to rotate asthe bra-rider moves pastfi't, thereby forming'what'is known as'a .Tibb'oir branding upon the pipe, the perimeter oi the bran'der be ng lubricated as explained above.
